An Urban Guru.
An inspiring person with good advice and an objective opinion, also with few airs and graces.
Usually in the yogic sense but also adaptable to cultural experts or humanitarians.
Usually slightly older as it takes time and experience to become a Gurbanuru.

On the way home I bumped into a Gurbanuru on the subway...this totally random person who gave me incredible advice on love and relationships.

A Gurbanuru knows what the world we live in is really like and has a good balance of enlightenment and practically; also a good understanding of popular culture.
